<desc>Creates a bolt of lightning. This will then move from the starting position (iX, iY) at the specified speed and the specified deviation (iXRange, iYRange). Setting the deviation values to 0 would create a straight, linear bolt.<br/>Coordinates are global, even in local calls.</desc>
<examples>
<example>
<code>LaunchLightning(<funclink>Random</funclink>(<funclink>LandscapeWidth</funclink>()), 0, -20, 41, +5, 15);</code>
<text>This call creates normal weather lightning.</text>
</example>
<example>
<code>LaunchLightning(100, 100, +5, 15, -10, 21);</code>
<text>This will create a bolt such as the one in the magic lightning spell, directed to the right.</text>
